Annual Mortality Rate and Causes of Death in a Hemodialysis Unit at a Rural Community Hospital in Chile: A Retrospective Cohort Study.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionMortality among patients receiving chronic hemodialysis remains substantially higher than in the general population, with cardiovascular and infectious diseases as the leading causes of death. Data from rural, low-complexity community hospitals are limited. In geographically remote areas, factors such as long distances to higher-complexity referral centers and potential delays in access to specialized care may influence patient outcomes. This study aimed to determine the annual mortality rate and causes of death in a cohort of chronic hemodialysis patients treated at a rural community hospital in Chile.
methodsWe conducted a retrospective cohort study including all adult patients receiving maintenance chronic hemodialysis at our center between January 1, 2025, and January 31, 2026, corresponding to a 13-month observation period. Transient patients who were temporarily dialyzed at our unit for less than two months before returning to their original dialysis center were excluded. Total patient-years were calculated, and mortality was expressed as deaths per 100 patient-years with 95% confidence intervals.
resultsA total of 59 patients were included (mean age 65 ± 14.7 years; 69.4% male). During follow-up, 13 patients died, accounting for 53.45 patient-years. The overall mortality rate was 24.3 deaths per 100 patient-years (95% CI: 13.0-41.6). Cardiovascular causes accounted for 61.5% of deaths, infectious causes for 30.7%, and traumatic causes for 7.6%. Six patients initiated dialysis during the study period; in this subgroup, the mortality rate was 56.5 deaths per 100 patient-years.
conclusionThe observed mortality rate was slightly higher than rates reported in large international registries. Although limited by the small number of patients in a single rural dialysis unit, these findings underscore the importance of continued outcome monitoring in rural dialysis units and suggest that structural and geographic factors may influence patient survival.
